How to use fertilizer ?

[mrmojorisin345]

Hello ! I have two plants that are approximately three weeks old, and I just bought 5$ plant fertilizer (some water soluble blue powder stuff) at my local hardware store. I'll post pictures below. My question is ; what quantity should I put and how to use it, do I just follow the directions written on the back of the product or ? I need advice, I'm a huge newbie haha And I'm also wondering ; when should I start to fertilize them ? Thank you for your answers !

Start with a 1/4 dose, go easy, it's easy to burn on with just a little to much.

Should I start adding the fertilizer now or should I wait until they get bigger ?

I agree with starting with about a 1/4 dose, but before you go ahead and do that, we need to know what medium you're growing in. Many mediums are rich in fertilizers, and can last several weeks before you need to add more. Likewise, some mediums are completely inert, which means you need to feed pretty well as soon as the plants sprout.

What kind of dirt are those growing in? There should be enough nutrients int he dirt to last them until you repot into bigger pots. And then once you repot into fresh dirt, they should have enough nutrients to last another 4-8 weeks. That stuff you bought is super concentrated. Be very careful with it.

Well the soil in which they are in right now is some soil that I legit dug up in my backyard, but for when but for the transfer I bought a bag of black soil

Thank you guys for your help by the way, so from what I understand so far ; I should add a reeeeeally small amount of the fertilizer I bought in some water, and wait until I put them into bigger pots before watering them with it ?

make sure the ph is right and when the plant starts losing its color start feeding a small amount of nutrients

Let's say I put like half a teaspoon of my blue powder stuff in a liter of water, is it too much ?

buy soil to start, don't bring outside problems indoors. I always separate mine, no cross contams.

Your ferts will work for vegging, For flowering you'll need to lower your 3 numbers (20-20-20). i prefer higher first number, lower other 2 during veg, like 24-8-6, Or close to that, during veg Looking for 5-15-5, 10-30-10, 0-10-10, for flower, get the idea, my growmie friend.

is there like a chart or directions on the bottle?

Yes there is but from what I understand it is really potent

To be honest I'm such a noobie that I don't know what all of that means A buddy of mine gave me seeds and I wanted to give it a shot, but I really don't want to fuck it up D:

well understanding the potency would help dilute to a correct amount, also as stated by @Skewbong might be a good idea to invest in a more tuned to flower fertilizer when your plants start going into the budding period

Does the label say per gallon or litre. Do the math, 3.8 L/gal. If its dose is for indoor 1/2 tsp per gal, and 1-1/3 TBSP PER gal for outdoor, use indoor schedule until its bigger then you can slowly increase from indoor amount to outdoor amount. I didnt read your label. Its common to see those ratios. Be careful if your adding something else. You cannot add a different nute, unless you have another gallon of new water. If you add 2 nutes to same 3.8 litres you have to cut nutes in half, so you don't nuke her, its the total nutes per gallon. Hope that helps.
